This is utter nonsense. I'd much rather have the input be difficult as there's a greater chance that a player will mess it up under the pressure of competitive play, it means there's a level of risk to something that makes Honda's jabs fucking Godlike. It makes no fucking sense to make piano-tapping easier if the game still includes any form of tricky execution through links, hell why not make the reversal time even more lenient while you're at it? :lol
Also anybody can learn how to piano-tap with enough practice, and as was mentioned earlier it will screw things up for people who can't be arsed to learn and just slide anyway because it's impossible to get from jab to fierce with just 4 inputs.
As for people who benefit from practicing their inputs, that's kind of the point. What you're asking for is a game which will auto-combo after you hit a normal, I mean why even make a player need to hit confirm given the practice that would take? Which is something SF4 isn't.
(Also didn't the updates say that jab hands is harder now? Which means Capcom agrees with me... which means I'm probably wrong on this
)
